This paper offers a post-colonial analysis of past and present representations of the archaeological remains of Roman Britain and Roman London in the British Museum and Museum of London respectively. Since post-colonial criticism of Romano-British archaeology is highly relevant to such an analysis, a brief description is provided at the outset. Thereafter follows a series of six case studies — three for each museum. The first four focus on the history of the Romano-British collections at both museums and sometimes draw on post-colonial insights to explain the development of these collections and the ways in which they were exhibited. The last two case studies investigate how British post-colonial criticism of Roman archaeology has (or has not) impacted on the current displays of the Romano-British collections at both museums. Finally, some recommendations will be offered based on the outcomes of these two case studies. Recurring themes are the representation of: the Roman military; Roman imperialism; the (material) culture of Roman Britain and Roman London.
